I also pressure washed the engine and decided to pop the intake off. I figured it had some stuck valves, as it wanted to fire but would just pop out the carb. Sure enough, 3 stuck intake valves. I have them soaking now. I'm hoping I can get the free without pulling the heads. I'm sure once they are free, it will run. This engine is very clean and untouched. That red paint is original, and notice the "X" mark on the head...I'm sure that is a factory mark
